WHAT IS GLAUCOMA?
It is a compound eye disease that causes damage to the optic nerve which further leads to irreversible, progressive vision loss. It is the second dominant cause of blindness.
Laser surgery is a desirable option as a transitional step between traditional surgery and drugs.
Laser Eye Surgery in India is provided by the best doctors at renowned hospitals that are equipped with the latest technology and at a much lower cost as compared to other western countries.
Laser Trabeculoplasty may be recommended by your doctor as an initial surgical option if you have an open-angle glaucoma and the disease is progressing even after prescribed medication.
The two types of laser surgery for glaucoma are:
- Argon Laser Trabeculoplasty (ALT)
- Selective Laser Trabeculoplasty (SLT)
Both the procedures are effective. The two procedures are different in a few ways. In case of SLT, a low-level of laser beam is used (sometimes known as cold laser). Whereas, ALT uses heat. Both the methods are safe and effective.
HOW TO PREPARE FOR LASER TRABECULOPLASTY?
Before and after the treatment, eye drops will be put in your eyes to reduce the amount of fluid. This prevents increased pressure in eye after the laser treatment.
LASER TRABECULOPLASTY PROCEDURE
Anaesthesia or numbing drops will be given to numb your eyes. A slit lamp microscope and lens will be used by your surgeon to guide the laser beam to the trabecular meshwork where fluid drains from the eye. The entire process takes about ten minutes.
A glaucoma drop, as well as an anti-inflammatory drop, will be administered by your surgeon immediately before and after the surgery to prevent post-operative inflammation.
AFTER THE PROCEDURE
Your sight may be blurry, and you may feel irritation in your eyes after the procedure.
You will be prescribed anti-inflammatory eye drops that you will have to take for several days post-operation.
Also, your doctor will schedule a post-operative appointment to assess results of your surgery.
Laser Iridotomy is suitable for people who have primary closed-angle glaucoma. Closed glaucoma is when the space between the sclera and the iris becomes so narrow that space is completely gone.
Laser Iridotomy aims to create a small hole in the iris to balance the pressure behind the iris and opening up the angle to permit the aqueous humour to flow.
HOW TO PREPARE FOR LASER IRIDOTOMY?
You will be advised to stop taking anti-inflammatory medications (like aspirin) as well as blood thinners (like Plavix).
LASER IRIDOTOMY PROCEDURE
An hour before the procedure, eye drops will be put in your eyes to make your pupil smaller, keep IOP in control, and to stretch your iris during the surgery. After about an hour, your eyes will be made numb with an anaesthetic. You will be made to sit at a machine (like a slit lamp microscope used during examination of the eyes). While focusing on the target, your surgeon will begin the laser treatment. The procedure is painless.
AFTER THE PROCEDURE
Some mild discomfort may be felt after the procedure and during the first few days. Your surgeon will prescribe anti-inflammatory drops that you will have to use for about a week after the process. There are no such restrictions after the surgery; you can resume your healthy lifestyle.
Above mentioned are the two types of laser surgery treatment for glaucoma. The best treatment option for you will be advised by your surgeon on the basis of certain examination. Make sure to follow your doctor’s advice.
